Delivering 3D advertising to mobile phones.
Directing advertising to mobile phones currently is limited to commercial text messages, short-code text-back messages, two dimensional (2D) images, or wireless access protocol (WAP) clickable push links. All of these traditional methods do not facilitate advertising approach were consumers can interact with prospective purchases. In this paper we introduce a novel and highly interactive location- and permission-based advertising system that allows 3D product adverts to be displayed on users' mobile phones. The paper provides a thorough discussion of the system covering its performance, implementation structure, platform-dependent optimizations and suggestions for future work. With mobile phones and 3D interactive tools, advertising becomes more engaging, rewarding and entertaining and provides marketing executives with new means of directing their campaigns to a more specific target audience
Trade Technology and Employment: A case Study of South Africa
This paper provides a comprehensive analysis of the impact of trade on employment in South Africa. Firstly, it considers the correlation between trade liberalisation and factor demand in South African manufacturing during the 1990s. Secondly, it investigates the impact of trade on labour using a Chenery (1979) style decomposition technique, following Edwards (2001a, 2001b, 2005b) and Jenkins (2002). It develops the earlier work by exploring both the indirect and the indirect effects and investigating variations in the regional impact of trade on factor demand during the 1990s. This suggests that technological change accounts for the bulk of jobs lost in manufacturing during the 1990s. To investigate, whether this reflects exogenous technological change or trade-induced technological change requires undertaking an econometric analysis and this explores the impact of trade on technological change through an induced labour demand model. This finds a strong effect of exogenous technological progress but only limited evidence that increased trade flows and trade liberalisation induced improvements in labour productivity.Trade; technology; employment; industrial panel
Mobslinger: The Fastest Mobile in the West.
Whilst there is a number of location sensing games emerging for mobile phones, from both commercial and academic sectors, there are few examples of social proximity based games that are effectively position independent. Bluetooth would seem an obvious choice for proximity based games, although the majority of games produced to-date simply uses it to provide a quasi peer to peer connection between users of multiplayer games. This is no-doubt due to the fact that proximity can often be implied from other location sensing technologies and that Bluetooth is often perceived as difficult to employ. In this paper we will show that Bluetooth can provide exciting game scenarios that can enable spontaneous stimulated social interaction using only proximity information. We illustrate this through the design rationale and subsequent implementation of âmobslingerâ which is a wild west, quick draw, âshoot-em-upâ game using mobile phones

Cathodoluminescence hyperspectral imaging on the nanometre scale
Extending cathodoluminescence microscopy into the hyperspectral imaging mode brings significant benefits to an already powerful nano-scale characterization tool. In this paper, we give an introduction to the technique, and illustrate its potential with examples of its application to both semiconducting and plasmonic nanostructures

Taxonomic assessment of two pygopodoid gecko subspecies from Western Australia
Abstract
Subspecies designations for herpetofauna in Western Australia were largely coined in the 20th century where rigorous evolutionary concepts to species were not consistently applied. Rather, subspecies tended to designate geographic populations of similar-looking taxa to nominate forms, usually differing in size, pattern or colour and, at best, a few scalation differences. Here we re-evaluate two pygopodoid taxa from Western Australia using a combination of published and original genetic data coupled with a reassessment of morphology. We review these differences in light of an integrative taxonomic approach that looks to find multiple independent lines of evidence to establish the evolutionary independence of populations. For the pygopod species Pletholax gracilis, we found consistent diagnostic characters (e.g. body size, visibility of ear opening, scalation) and a deep genetic divergence between the two subspecies. We therefore raise each subspecies to full species: P. gracilis and P. edelensis. The two subspecies of the carphodactylid gecko Nephrurus wheeleri were also assessed, and we found strong genetic and morphological evidence (e.g. body size, scalation, pattern) to raise these to full species: N. wheeleri and N. cinctus. By revisiting Storrâs morphological insights and newly acquired genetic evidence, in addition to a thorough re-examination of morphological traits, our study provides a robust foundation to raise Storrâs morphological subspecies into full species based upon multiple lines of evidence. Such an approach applied to other subspecies in the Australian herpetofauna also may result in revised taxonomies

Working for Ford Forty Years On
Huw Beynonâs Working for Ford achieved celebrity when published in 1973. An assessment 40 years later identifies the lasting value of the book. Though written from a clearly stated point of view, it did not present a biased account, and it included much information permitting alternative assessments. It is also possible to construct an explanation of why the situation was as it was; this explanation turns on the technology of car plants, distinctive strategies adopted by Ford management, and the active role of workers. Though the particular events analysed in the book were of their time, the book is of more than historical interest. Its lasting value is four-fold: it explains how and why workers engage in immediate battles for control of the workplace; it indicates that workers do not choose such battles willingly and are often aware of wider concerns while lacking the means to pursue them; it points to substantial areas of continuity with the contemporary organization of labour and struggles for workersâ dignity; and it permits reflection on the possibilities of organized alternatives to current forms of work organization
